"We will go on, try our hardest, never give up and make the best of the life we have," they wrote.

"We consider ourselves immensely fortunate to have received the love, solidarity and support from so many kind and decent people over the last decade. There have been many challenges and low points along the way but the warmth, encouragement and positivity we have experienced from the ‘quiet majority’ has undoubtedly sustained us and maintained our faith in human goodness. And while that is there, there will always be hope.'

Kate and Gerry McCann recently spoke to Sunday Night about the case, and their frustrations with the Portuguese police, who named them as prime suspects at the time and didn’t start a search for her kidnappers until 4.30am – hours after she was reported missing at around 10pm.

"The ludicrous thing is that Madeleine died in the apartment by an accident and we hid her body," Mr McCann told Sunday Night. "Well, when did she have the accident and die? 'Cause the only time she was left unattended was when we were at dinner, so if she died then, how could we have disposed of or hidden her body? You know, when there was an immediate search?”
